[LSJ] Undying Thirst/Peacemaker combo

[François]

Hello,

A vampire is in torpor.
Meanwhile, another bleeding vampire is blocked by a Baali. That Baali
then plays Undying Thirst ( this vampire cannot take any action other
than diablerie) and then PeaceMaker (the action continues as if
unblocked).

Does the bleed fizzle, for the acting vampire would not be able to
attempt it due to Undying Thirst ? or does the action continue as
normal ?

Thank you,

François

Continues as normal.
Much like a vampire bleeding who spends his last blood on a Form of
Mist -- the action continues even though the acting vampire couldn't
start the action empty (since he'd have to hunt instead).
